Don’t plant thorny trees directly opposite the front door of your home or on the roadside! Feng Shui believes that thorny trees are planted to ward off evil spirits. Nowadays, many people plant an anise tree in the middle of their yard, which is wrong. Why should we avoid evil spirits when everything is going well at home? It is best to plant anise thorns on the west and north sides of your home, and avoid planting them where you will encounter them while walking.
